[R] cmdscale(eurodist)

[Paul Lemmens]

Dear all,

I have a question regarding the 'y <- -loc[,2]' in ?cmdscale.
Although I see that the plot is more sensible when using the '-loc'
instead of just 'y <- loc[,2]', I don't understand if there is a
statistical reason to do '-loc[,2]'.  So is this just to make the
graph look better, or should I always use -loc for the y-axis of a
similar plot for a completely different data set.

Kind regards,
Paul Lemmens
